Description

Pericom Semiconductor’s PI3L series of logic circuits are produced

using the Company’s advanced submicron CMOS technology.

The PI3L100 is a Quad 2:1 multiplexer/demultiplexer LanSwitch

with three-state outputs. This device can be used for switching

between various standards, such as 10 Base-T and 100 Base-T.

Generally, this part can be used to replace mechanical relays in low

voltage LAN applications that have physical layer, unshielded

twisted pair media (UTP) with either CAT 3 or CAT 5 grade cable.
